Tube Plugs
Precision-machined tube plugs for safely isolating leaking or damaged heat exchanger and boiler tubes — in every size and material for every application.
RELIABLE TUBE ISOLATION
When a heat exchanger tube fails, fast and reliable plugging is critical to restoring operation. Elliott tube plugs are machined to precise tolerances for a leak-proof seal in every application.
We manufacture tapered plugs, mechanical plugs, and drive plugs in virtually every material — copper, brass, carbon steel, stainless, titanium, and high alloys.
Key Features
- Available for virtually every tube size and OD
- Copper, brass, carbon steel, stainless, titanium
- Tapered, mechanical, and drive-type configurations
- Precision machined for leak-proof sealing
- ASME and TEMA compliant designs available
- Made in USA — fast delivery from stock

- Available in hundreds of standard sizes
- Copper, brass, carbon steel, stainless
- Fast delivery from stock
- Lowest cost per plug
Configurations
Mechanical Tube Plugs
Torque-applied mechanical plugs for applications requiring positive seating and retrievability.
Mechanical tube plugs use a tapered pin and expander body to create a positive mechanical lock in the tube. They can be retrieved and reused if necessary.
Features
- Positive mechanical lock — no movement after installation
- Retrievable design for tube inspections
- Torque wrench installation for consistent seating
- Suitable for high-pressure applications
- Stainless steel and specialty alloys available
